Stay ready and tie your seatbelts now for an amazing journey of knowledge.

Here are the 16 Marvelous Facts about Earth which will force you to think and research about them but, don’t bother as we will provide you with the best and genuine info.

  1.   You are moving even you are at rest.

Don’t get shocked now. It is true that even if you are resting or sitting at any place, you are moving at a very high pace. Wonder, how?

It is because of Earth’s rotation and revolution. Earth’s rotational speed is about 460 meters per second or casually 1000 miles per second. Isn’t it enough to prove the above-written fact? If no, then go for the speed of revolution of Earth.

The Earth revolves at a fierce speed of 30 km per second. Oh! It is absolutely a great speed.

  2.   More than 95% of the oceans on Earth are still unexplored.

Now, you might be thinking that we travel by ships and the network of ships is very large, right? But, do you know that ships follow a pre-defined route. They never take shortcuts and the routes are previously decided by the captains and officers.

So, we can now say that we are still unaware of more than 90% of the oceans and its creatures as well.

And, yes! Sometimes, some videos go viral representing some abnormal creatures. I’m sure you have watched them too.

It might be possible that they are the videos of real and original creatures about which we are unaware.

The scientists and astrologers are discovering new creatures and places day-by-day. This is enough to point out that we are unaware of most of the creatures whether they are terrestrial or aquatic.

  3.   Earth possesses a strong magnetic field.

    Earth along with all members of the solar system and stars possess a strong magnetic field that holds the ozone layer from being flushed away by the solar winds of space.

    Many thanks to the Earth’s magnetic field because of which compass works on Earth. If the magnetic field was not present on Earth, possibly, no life could have ever sustained on Earth.

  4.   About 99% of the species are already extinct.

It seems to be a fake sentence but it is the truth. Approximately 98-99% of the total species found on Earth which existed in the time of dinosaurs and even earlier, are now extinct and not found on the planet.

The main reason for this was not any abnormal activity but old age. 

There are tons of websites and blogs that state different-different opinions but opinions are not the truth.

The truth is that there was a series was five consecutive waves of extinction that wiped out most of the living species which were known to be found on Earth.

  5.   Earth’s core is as hot as Sun’s surface.

Hey! Hey! Don’t get shocked. I am not saying that Earth is hotter than the Sun. I am saying that Earth’s core is as hot as Sun’s surface.

The average temperature in the core of Earth is about 5200 Celsius whereas the temperature at the surface of the Sun is known to be around 5505 Celsius. This is not the same but we can say that they both are approximately the same in common words.

  6.   Earth is the only planet to have tectonic plates.

The whole system of tectonic plates is found only on our planet. As you know that the Earth’s crust is floating on the molten magma which is in the mantle and core. We observe earthquakes only due to tectonic plates.

If we compare another planet say, Mars, then Mars does not have tectonic plates but Earth has.

This is one of the reasons that make our planet the most unique among all other planets.

  7.   We live on the densest planet of the solar system.

Yes, we live on the densest planet of our solar system. If we compare the density of Earth with other members of the solar system, then we’ll find that Earth has the highest density among all others.

For your kind information, Earth’s density is known to be 5.51 gm/cm3.

Let’s have a look at the consecutive densities of the planets of our solar system.

  • Mercury – 5.4 gm/cm3
  • Venus – 5.2 gm/cm3
  • Earth – 5.5 gm/cm3
  • Mars – 3.9 gm/cm3
  • Jupiter – 1.3 gm/cm3
  • Saturn – 0.7 gm/cm3
  • Uranus – 1.3 gm/cm3
  • Neptune – 1.6 gm/cm3

  8.   Do you know why we observe leap year every 4 years?

You know that Earth takes 365 days to complete a revolution around the Sun, right?

No, you’re completely wrong. Earth takes 365.25 days to revolve once around the Sun. Therefore, a day is added every 4 years to balance the calendar year and the tropical year (period of Earth’s revolution).

  9.   All planets are named after a Greek/Roman God except Earth.

Here comes an extraordinary fact. You might not know that every planet in the solar system is named after the name of a Greek God except our planet i.e. Earth. Let’s have a brief look at every name of our solar system.

  • Mercury – named after Roman Diety ‘Mercury’
  • Venus – named after Roman Goddess ‘Aphrodite’

10.    The speed of Earth’s rotation is slowing down.

Yes! The speed of earth’s rotation is slowing down because of tidal effects the moon has over-rotation of Earth. If we consider the atomic clock, it shows that the duration of the day today is longer by 1.7 milliseconds as compared to the days of about 100 years back.

Roughly, Earth’s rotation has slowed by 6 hours in the last 2740 years. 

Moon’s gravity is STRONG!!

11.    Earth was believed to be the center of the universe.

If we observe the geocentric model of astronomy, it states that Earth is the center of the universe, and all other astronomical bodies like moon, sun, stars, and planets revolve around the Earth.

But today, we all know it is not true, right?

Later on, Nicolaus Copernicus developed the heliocentric model of astronomy in the 16th century which stated that Sun was the center of the universe with all other astronomical bodies revolving around it.

12.    Earth’s first-ever photograph was clicked in 1946.

Rocket scientists clicked the first-ever photograph of Earth from Space on 24 October 1946. This photo was captured from an aircraft 105 km above the ground which was launched from White Sands Missile Range situated in New Mexico, United States.

Have a look at the below-attached photograph. Isn’t it looking astonishing? Yeah, it is the photo of our planet.

13.    Our planet mostly comprises magnesium, iron, oxygen, and silicon.

These four elements account for about 91.2% of the total mass of Earth. For your information, the mass of our planet is about 5.98 x 1024 kg.

Considering every element, the chart may go like this:

  • Iron = 32.1%
  • Oxygen = 30.1%
  • Silicon = 15.1%
  • Magnesium = 13.9%

Adding all these, the answer will be the same as I stated above.

14.    The most active volcano of the planet is Kīlauea.

You already know that numerous volcanoes have gone inactive after the extinction of dinosaurs, but do you know that some volcanoes are still alive and possess the power of destroying its surroundings up to a few kilometers? No?

So, let me tell you that Kīlauea is the most active known volcano on the entire planet situated in the Hawaiian Islands that last erupted between 1983 and 2018.
